The original equations have been restored to the WR Sheet. Of course if equations have to be modified or added because of the new variables, equation editing and copying features can be used to modify the equations. But at least you can start out with the old ones; you do not have to re-create them. For example you have to add rows to three equations for the new Category QWC.
